Giant 20' x 3' x 2' router build

[charlieuk]

Just started building 3 aixis cnc aprox 20' x 3' x 2' I am building it from 80mm aluminium extrusion and using a 20mm hywin rail system on all 3 axis with rack and pinion on x and y and a ball screw on the Z. It is a cantilever arm style machine and will mainly be used for cutting foam and other reactively soft materials.

The aluminium i have purchased from KJN and the motion control and linear movement parts are being supplied by CNC4YOU who have been exceedingly helpful and a great bunch of guys.

It is still at very early stages but i do have a few pics of the frame coming together which i will post a little latter. I look forward to any feed back or advice.
